Available in PDF, EPUB and Kindle. Book excerpt: International trade is dominated by a small number of very large firms. Models of trade with heterogeneous firms have been developed to study the causes and consequences of this observation. The canonical model of trade with heterogeneous firms shows that trade leads to between-firm reallocations and selection: it shifts employment towards firms with the best attributes and forces marginal firms to exit. The model also illustrates the role of heterogeneity, and its various sources, in explaining the volume of trade and the firm-level margins of adjustment. Consistent with the model, earlier empirical studies have documented that exporting is a rare activity, that exporting firms are larger and more productive than other firms, and that trade liberalization reallocates market shares towards the best-performing firms in various countries. More recent studies using transaction-level data have unveiled additional salient features of trade flows. First, sales by foreign firms are very heterogeneous and highly concentrated. Second, both the extensive margin (number of exporting firms) and the intensive margin (average export per firm) are important in explaining the level of exports and its changes over time. More heterogeneity in sales across firms is associated with a higher volume of trade along both margins. Third, increased foreign competition reallocates market shares towards top firms and hence can increase concentration from any country of origin. Numerous extensions of the benchmark model have been proposed to study other important aspects, such as the relevance of multi-product and multinational firms and the extent to which heterogeneity is endogenous to firms' choices, but some open challenges still remain.

Download or read book International Trade written by Jonathan Eaton and published by . This book was released on 2012 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A recent literature has introduced heterogeneous firms into models of international trade. This literature has adopted the convention of treating individual firms as points on a continuum. While the continuum offers many advantages this convenience comes at some cost: (1) Shocks to individual firms can never have an aggregate effect. (2) It is hard to reconcile the small (sometimes zero) number of firms engaged in selling from one country to another with a continuum. (3) For such models to deliver finite solutions for aggregates, such as the price index, requires restrictions on parameter values that may not hold in the data. We show how a standard heterogeneous-firm trade model can be amended to allow for only an integer number of firms. The model overcomes the deficiencies of the continuum model enumerated above. Taking the model to aggregate data on bilateral trade in manufactures among 92 countries and to firm-level export data for a much narrower sample shows that it accounts for both the large share of a small number of firms in sales around the world and for zeros in bilateral trade data while maintaining the good fit of the standard gravity equation among country pairs with thick trade volumes. Randomness at the firm level adds substantially to aggregate variability.

This book was released on 2018 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbook of Computational Economics and Finance provides a survey of both the foundations of and recent advances in the frontiers of analysis and action. It is both historically and interdisciplinarily rich and also tightly connected to the rise of digital society. It begins with the conventional view of computational economics, including recent algorithmic development in computing rational expectations, volatility, and general equilibrium. It then moves from traditional computing in economics and finance to recent developments in natural computing, including applications of nature-inspired intelligence, genetic programming, swarm intelligence, and fuzzy logic. Also examined are recent developments of network and agent-based computing in economics. How these approaches are applied is examined in chapters on such subjects as trading robots and automated markets. The last part deals with the epistemology of simulation in its trinity form with the integration of simulation, computation, and dynamics. Distinctive is the focus on natural computationalism and the examination of the implications of intelligent machines for the future of computational economics and finance. Not merely individual robots, but whole integrated systems are extending their "immigration" to the world of Homo sapiens, or symbiogenesis.
Download or read book The Intensive Margin in Trade written by Ana Fernandes and published by International Monetary Fund. This book was released on 2018-12-07 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank’s Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50 percent of variation in exports is along the extensive margin—a quantitative victory for the Melitz framework. The remaining 50 percent on the intensive margin (exports per exporting firm) contradicts a special case of Melitz with Pareto-distributed firm productivity, which has become a tractable benchmark. This benchmark model predicts that, conditional on the fixed costs of exporting, all variation in exports across trading partners should occur on the extensive margin. We find that moving from a Pareto to a lognormal distribution allows the Melitz model to match the role of the intensive margin in the EDD. We use likelihood methods and the EDD to estimate a generalized Melitz model with a joint lognormal distribution for firm-level productivity, fixed costs and demand shifters, and use “exact hat algebra” to quantify the effects of a decline in trade costs on trade flows and welfare in the estimated model. The welfare effects turn out to be quite close to those in the standard Melitz-Pareto model when we choose the Pareto shape parameter to fit the average trade elasticity implied by our estimated Melitz-lognormal model, although there are significant differences regarding the effects on trade flows.

Available in PDF, EPUB and Kindle. Book excerpt: What conclusions can be drawn from recent advances in international trade and international macroeconomics? New datasets, theoretical models, and empirical studies have resulted in fresh questions about the world trade and payment system. These chapters--six on trade and six on international macroeconomics--reveal the richness that researchers have uncovered in recent years. The chapters on foreign trade present, among other subjects, new integrated multisector analytical frameworks, the use of gravity equations for the estimation of trade flows, the role of domestic institutions in shaping comparative advantage, and international trade agreements. On international macroeconomics, chapters explore the relation between exchange rates and other macroeconomic variables; risk sharing, allocation of capital across countries, and current account dynamics; and sovereign debt and financial crises. By addressing new issues while enabling deeper and sharper analyses of old issues, this volume makes a significant contribution to our understanding of the global economy. Systematically illuminates and interprets recent developments in research on international trade and international macroeconomics Focuses on newly developing questions and opportunities for future research Presents multiple perspectives on ways to understand the global economy
Download or read book Comparative Advantage and Heterogeneous Firms written by Andrew B. Bernard and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines how country, industry and firm characteristics interact in general equilibrium to determine nations' responses to trade liberalization. When firms possess heterogeneous productivity, countries differ in relative factor abundance and industries vary in factor intensity, falling trade costs induce reallocations of resources both within and across industries and countries. These reallocations generate substantial job turnover in all sectors, spur relatively more creative destruction in comparative advantage industries than comparative disadvantage industries, and magnify ex ante comparative advantage to create additional welfare gains from trade. The relative ascendance of high-productivity firms within industries boosts aggregate productivity and drives down consumer prices. In contrast with the neoclassical model, these price declines dampen and can even reverse the real wage losses of scarce factors as countries liberalize.
Download or read book Search Externalities in Firm to Firm Trade written by John Spray and published by International Monetary Fund. This book was released on 2021-03-19 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: I develop a model of firm-to-firm search and matching to show that the impact of falling trade costs on firm sourcing decisions and consumer welfare depends on the relative size of search externalities in domestic and international markets. These externalities can be positive if firms share information about potential matches, or negative if the market is congested. Using unique firm-to-firm transaction-level data from Uganda, I document empirical evidence consistent with positive externalities in international markets and negative externalities in domestic markets. I then build a dynamic quantitative version of the model and show that, in Uganda, a 25% reduction in trade costs led to a 3.7% increase in consumer welfare, 12% of which was due to search externalities.
Download or read book A Practical Guide to Trade Policy Analysis written by Marc Bacchetta and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trade flows and trade policies need to be properly quantified to describe, compare, or follow the evolution of policies between sectors or countries or over time. This is essential to ensure that policy choices are made with an appropriate knowledge of the real conditions. This practical guide introduces the main techniques of trade and trade policy data analysis. It shows how to develop the main indexes used to analyze trade flows, tariff structures, and non-tariff measures. It presents the databases needed to construct these indexes as well as the challenges faced in collecting and processing these data, such as measurement errors or aggregation bias. Written by experts with practical experience in the field, A Practical Guide to Trade Policy Analysis has been developed to contribute to enhance developing countries' capacity to analyze and implement trade policy. It offers a hands-on introduction on how to estimate the distributional effects of trade policies on welfare, in particular on inequality and poverty. The guide is aimed at government experts engaged in trade negotiations, as well as students and researchers involved in trade-related study or research. An accompanying DVD contains data sets and program command files required for the exercises. Copublished by the WTO and the United Nations Conference on Trade and Development

Available in PDF, EPUB and Kindle. Book excerpt: Changing Patterns of Global Trade outlines the factors underlying important shifts in global trade that have occurred in recent decades. The emergence of global supply chains and their increasing role in trade patterns allowed emerging market economies to boost their inputs in high-technology exports and is associated with increased trade interconnectedness.The analysis points to one important trend taking place over the last decade: the emergence of China as a major systemically important trading hub, reflecting not only the size of trade but also the increase in number of its significant trading partners.
Download or read book Trade Theory in Computable General Equilibrium Models written by Peter B. Dixon and published by Springer. This book was released on 2018-03-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for people who want to understand modern trade theory, particularly the Melitz model. It lays out Melitz theory from first principles and relates it to earlier theories of Armington and Krugman. For trade theory specialists, the book produces some significant conclusions. It identifies conditions under which Krugman and Melitz models produce essentially the same results for the welfare effects of trade liberalization as those obtained from Armington, and conditions under which this is not true. These findings will be of interest to academics and policy advisors who need to understand critiques of Armington by proponents of Krugman and Melitz. For computable general equilibrium (CGE) modelers, the book shows how Melitz-style CGE models can be calibrated, solved and interpreted. A major practical contribution of the book is to show how large-scale Armington models such as GTAP can be converted to Melitz by the addition of a small number of equations and minimal alteration of the original Armington model. The book describes computational experience in solving Melitz CGE models using GEMPACK software. This experience will be of interest to researchers currently attempting to solve Melitz-based CGE models. Almost all previous Melitz studies have used GAMS software. Authors of these studies have reported computational difficulties. These difficulties did not occur in this book’s GEMPACK-based computations. The book concludes that: (a) CGE modelers can embrace Melitz while retaining their Armington-based models as powerful interpretive devices; and (b) via GEMPACK, large-scale CGE models incorporating Melitz specifications can be solved with no more difficulty than similar-dimensioned Armington models.
